  • BACKGROUND OF THE INVENTION
  • 1. Technical Field of the Invention
  • This invention relates generally to wireless systems and more particularly to wireless devices that communicate with a remote game device.
  • 2. Description of Related Art
  • Communication systems are known to support wireless and wire lined communications between wireless and/or wire lined communication devices. Such communication systems range from national and/or international cellular telephone systems to the Internet to point-to-point in-home wireless networks to radio frequency identification (RFID) systems. Each type of communication system is constructed, and hence operates, in accordance with one or more communication standards. For instance, radio frequency (RF) wireless communication systems may operate in accordance with one or more standards including, but not limited to, RFID, IEEE 802.11, Bluetooth, advanced mobile phone services (AMPS), digital AMPS, global system for mobile communications (GSM), code division multiple access (CDMA), local multi-point distribution systems (LMDS), multi-channel-multi-point distribution systems (MMDS), and/or variations thereof. As another example, infrared (IR) communication systems may operate in accordance with one or more standards including, but not limited to, IrDA (Infrared Data Association).
  • Depending on the type of RF wireless communication system, a wireless communication device, such as a cellular telephone, two-way radio, personal digital assistant (PDA), personal computer (PC), laptop computer, home entertainment equipment, RFID reader, RFID tag, et cetera communicates directly or indirectly with other wireless communication devices. For direct communications (also known as point-to-point communications), the participating wireless communication devices tune their receivers and transmitters to the same channel or channels (e.g., one of the plurality of radio frequency (RF) carriers of the wireless communication system) and communicate over that channel(s). For indirect wireless communications, each wireless communication device communicates directly with an associated base station (e.g., for cellular services) and/or an associated access point (e.g., for an in-home or in-building wireless network) via an assigned channel. To complete a communication connection between the wireless communication devices, the associated base stations and/or associated access points communicate with each other directly, via a system controller, via the public switch telephone network, via the Internet, and/or via some other wide area network.
  • For each RF wireless communication device to participate in wireless communications, it includes a built-in radio transceiver (i.e., receiver and transmitter) or is coupled to an associated radio transceiver (e.g., a station for in-home and/or in-building wireless communication networks, RF modem, etc.). As is known, the receiver is coupled to the antenna and includes a low noise amplifier, one or more intermediate frequency stages, a filtering stage, and a data recovery stage. The low noise amplifier receives inbound RF signals via the antenna and amplifies then. The one or more intermediate frequency stages mix the amplified RF signals with one or more local oscillations to convert the amplified RF signal into baseband signals or intermediate frequency (IF) signals. The filtering stage filters the baseband signals or the IF signals to attenuate unwanted out of band signals to produce filtered signals. The data recovery stage recovers raw data from the filtered signals in accordance with the particular wireless communication standard.
  • As is also known, the transmitter includes a data modulation stage, one or more intermediate frequency stages, and a power amplifier. The data modulation stage converts raw data into baseband signals in accordance with a particular wireless communication standard. The one or more intermediate frequency stages mix the baseband signals with one or more local oscillations to produce RF signals. The power amplifier amplifies the RF signals prior to transmission via an antenna.
  • In most applications, radio transceivers are implemented in one or more integrated circuits (ICs), which are inter-coupled via traces on a printed circuit board (PCB). The radio transceivers operate within licensed or unlicensed frequency spectrums. For example, wireless local area network (WLAN) transceivers communicate data within the unlicensed Industrial, Scientific, and Medical (ISM) frequency spectrum of 900 MHz, 2.4 GHz, and 5 GHz. While the ISM frequency spectrum is unlicensed there are restrictions on power, modulation techniques, and antenna gain.
  • In IR communication systems, an IR device includes a transmitter, a light emitting diode, a receiver, and a silicon photo diode. In operation, the transmitter modulates a signal, which drives the LED to emit infrared radiation which is focused by a lens into a narrow beam. The receiver, via the silicon photo diode, receives the narrow beam infrared radiation and converts it into an electric signal.
  • IR communications are used video games to detect the direction in which a game controller is pointed. As an example, an IR sensor is placed near the game display, where the IR sensor to detect the IR signal transmitted by the game controller. If the game controller is too far away, too close, or angled away from the IR sensor, the IR communication will fail.
  • Further advances in video gaming include three accelerometers in the game controller to detect motion by way of acceleration. The motion data is transmitted to the game console via a Bluetooth wireless link. The Bluetooth wireless link may also transmit the IR direction data to the game console and/or convey other data between the game controller and the game console.
  • While the above technologies allow video gaming to include motion sensing, it does so with limitations. As mentioned, the IR communication has a limited area in which a player can be for the IR communication to work properly. Further, the accelerometer only measures acceleration such that true one-to-one detection of motion is not achieved. Thus, the gaming motion is limited to a handful of directions (e.g., horizontal, vertical, and a few diagonal directions.

  • DETAILED DESCRIPTION OF THE INVENTION
  • FIG. 1 is a schematic block diagram of an embodiment of a communication system in accordance with the present invention. In particular a communication system is shown that includes a communication device 10 that communicates real-time data 24 and non-real-time data 26 wirelessly with one or more other devices such as base station 18, non-real-time device 20, real-time device 22, and non-real-time and/or real-time device 25. In addition, communication device 10 can also optionally communicate over a wireline connection with non-real-time device 12, real-time device 14 and non-real-time and/or real-time device 16.
  • In an embodiment of the present invention the wireline connection 28 can be a wired connection that operates in accordance with one or more standard protocols, such as a universal serial bus (USB), Institute of Electrical and Electronics Engineers (IEEE) 488, IEEE 1394 (Firewire), Ethernet, small computer system interface (SCSI), serial or parallel advanced technology attachment (SATA or PATA), or other wired communication protocol, either standard or proprietary. The wireless connection can communicate in accordance with a wireless network protocol such as IEEE 802.11, Bluetooth, Ultra-Wideband (UWB), WIMAX, or other wireless network protocol, a wireless telephony data/voice protocol such as Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Enhanced Data Rates for Global Evolution (EDGE), Personal Communication Services (PCS), or other mobile wireless protocol, RFID of other RF tag protocol or other wireless communication protocol, either standard or proprietary. Further, the wireless communication path can include separate transmit and receive paths that use separate carrier frequencies and/or separate frequency channels. Alternatively, a single frequency or frequency channel can be used to bi-directionally communicate data to and from the communication device 10.
  • Communication device 10 can be a mobile phone such as a cellular telephone, a personal digital assistant, game device, personal computer, laptop computer, or other device that performs one or more functions that include communication of voice and/or data via wireline connection 28 and/or the wireless communication path. In an embodiment of the present invention, the real-time and non-real-time devices 12, 14 16, 18, 20, 22 and 25 can be a game console, access points, personal computers, laptops, PDAs, mobile phones, such as cellular telephones, devices equipped with wireless local area network or Bluetooth transceivers, FM tuners, TV tuners, digital cameras, digital camcorders, or other devices that either produce, process or use audio, video signals or other data or communications.
  • In operation, the communication device includes one or more applications that include voice communications such as standard telephony applications, voice-over-Internet Protocol (VoIP) applications, local gaming, Internet gaming, email, instant messaging, multimedia messaging, web browsing, audio/video recording, audio/video playback, audio/video downloading, playing of streaming audio/video, office applications such as databases, spreadsheets, word processing, presentation creation and processing and other voice and data applications. In conjunction with these applications, the real-time data 26 includes telephony data, voice, audio, video, multimedia data, display data, motion data, for application such as telephony, gaming, or other applications. The non-real-time data 24 includes text messaging, email, web browsing, file uploading and downloading, authentication data, user preferences, and other data used in any of the application discussed above.
  • In an embodiment of the present invention, the communication device 10 includes an integrated circuit, such as an RF integrated circuit that includes one or more features or functions of the present invention. Such features and functions shall be described in greater detail in association with FIGS. 5-65 that follow.
  • FIG. 2 is a schematic block diagram of an embodiment of another communication system in accordance with the present invention. In particular, FIG. 2 presents a communication system that includes many common elements of FIG. 1 that are referred to by common reference numerals. Communication device 30 is similar to communication device 10 and is capable of any of the applications, functions and features attributed to communication device 10, as discussed in conjunction with FIG. 1. However, communication device 30 includes one or more separate wireless transceivers for communicating, contemporaneously, via two or more wireless communication protocols with data device 32 and/or data base station 34 via RF data 40 and voice base station 36 and/or voice device 38 via RF voice signals 42.
  • FIG. 3 presents a pictorial representation of a wireless network 111 in accordance with an embodiment of the present invention. The wireless network 111 includes an access point 110 that is coupled to packet switched backbone network 101. The access point 110 manages communication flow over the wireless network 111 destined for and originating from each of communication devices 121, 123, 117 and 127. Via the access point 110, each of the communication devices 121, 123, 117 and 127 can access service provider network 105 and Internet 103 to, for example, surf web-sites, download audio and/or video programming, send and receive messages such as text messages, voice message and multimedia messages, access broadcast, stored or streaming audio, video or other multimedia content, play games, send and receive telephone calls, and perform any other activities, provided directly by access point 110 or indirectly through packet switched backbone network 101.
  • One or more of the communication devices 121, 123, 117 and 127, such as communication device 117 is a mobile device that can include the functionality of communication devices 10 or 30. In particular, communication device 125 includes an RF integrated circuit (IC) optionally including a motion sensor such as an accelerometer, RFID tag, or on-chip gyrating circuit that generates motion parameters based on motion of the device including a velocity, velocity vector, acceleration (including deceleration) and/or other motion parameter. In addition, communication device 117 optionally includes a GPS receiver that generates GPS position data and/or GPS velocity data. The RF IC processes the optional GPS position data and GPS velocity data and the optional motion parameters to produce motion data 113, such as position information and velocity information that identifies the location, velocity, orientation and/or direction of motion of the communication device 117. The RF IC can use data from either the optional motion sensor or the GPS receiver or both to generate the motion data. If for instance the GPS receiver is running and receiving a strong signal, GPS position and velocity data can be used to generate the motion data 113. If however, the GPS receiver is starting up, has lost satellite reception, the device is transmitting or the GPS receiver is otherwise generating inaccurate data, either the optional motion sensor or an extrapolation of past data can be used to generate velocity information and can further generate position information from the last know position coordinates and/or velocity.
  • In addition, where high data rate motion data 113 is required for an application, for instance a gaming application where the communication device is used to communicate motion data to a game console or game server in conjunction with a local game or an online game, the GPS receiver can generate a reference position and the optional motion sensor can be used to generate motion vectors or other different position data at sample periods such as 10 msec, 20 msec, 50 msec, 100 msec, or some other data sample period.
  • The RF IC optionally generates outbound data that includes the motion data 113 and/or a flag or other data that indicates communication device 117 is a mobile device, generates an outbound RF signal from outbound data and transmits the outbound RF signal to a remote station, such as the access point 110.
  • In operation, access point 110 can optionally change its own transmit and receive characteristics, based on the knowledge that communication device 117 is mobile, is in motion and/or based on information from a velocity vector or other motion data 113 that indicates that the communication device 125 is moving into closer range, is moving out of range, is moving close to a known source of interference, is moving into or away from an obstructed path, etc. Examples of transmit and receive characteristics include: transmit power levels; antenna configurations such as multi-input multi-output (MIMO) configuration, beam patterns, polarization patterns, diversity configurations, etc. to adapt the orientation and/or position of the communication device; protocol parameters and other transmit and receive characteristics of the access point.
  • In addition, access point 110 can generate optionally control data 99 to transmit to the communication device 117 and/or the communication devices 121, 123 and 127, to modify the transmit and receive characteristics of these devices. Further, in an embodiment of the present invention, access point 110 can generate a request to receive periodic motion data from the communication device 117. Alternatively, communication device 117 can generate and transmit motion data on a regular and/or periodic basis or in response to changes in motion data 113 that compare unfavorably (such as to exceed) a motion change threshold, such as to inform the access point 110 when the communication device 117 starts, stops, changes speed and/or direction, etc.
  • For example, communication device 117 can indicate to access point 110 that it is a mobile device, and access point 110 can request that communication device 117 send periodic motion data 113. If the access point 110 determines that the communication device 117 is moving out of range, it can increase its power level, and steer its antenna beam in the direction of the communication device 117 and command the communication device 117 to modify one or more if its transmit and/or receive parameters, to increase its power level, steer its antenna beam at the access point and/or to modify other antenna parameters to compensate for a possible lowering of signal to noise ratio, etc.
  • Further access point 110 can operate to manage the transmit and receive characteristics by the adjustment of the protocol or protocols used in communicating between the access point 110 and the client devices 121, 123, 117 and 127 and power levels inherent in and associated therewith. In one mode of operation, access point 110 can selectively adjust one or more protocol parameters, such as the packet length, data rate, forward error correction, error detection, coding scheme, data payload length, contention period, and back-off parameters used by access point 110 in communication with one or more of the client devices 121, 123, 117 and 127, based on the analysis of the motion data 113. In this fashion, the protocol parameters can be adapted to compensate for the motion of one or more communication devices, such as communication device 117, to conserve power, increase throughput, and/or to minimize unnecessary transmission power utilization based on the conditions of the network.
  • For example, in the event that a mobile client device, such as communication device 117 is anticipated to have difficulty detecting transmissions from communication device 123 because it is moving out of range, access point 110 can modify the protocol parameters so that transmissions by communication device 117 include more aggressive error correcting codes, increased back-off times and/or smaller data payloads or packet length to increase the chances that a packet will be received in the event of contention by communication device 123. In addition, decreasing the packet length can increase the frequency of acknowledgements transmitted by access point 110. These acknowledgements can be transmitted at a power level sufficient to be heard by communication device 123. With increased back-off times, communication device 123 has less opportunity to create a potential contention.
  • In a further mode of operation, access point 110 and communication devices 121, 123, 117 and 127 can operate using a plurality of different, and potentially complimentary, protocols having different protocol parameters. Access point 110 can likewise select a particular one of a plurality of protocols that suits the particular conditions present in the wireless network 111, as determined based on an assessment of motion data 113. For instance, an access point can select from 802.11(n), 802.11(g) or 802.11(b) protocols having different protocol parameters, data rates, etc, based on the particular protocol best suited to the current mobility status of communication devices 121, 123, 117 and 127.
  • While the description above has focused on the control of transmit and receive characteristics of communication devices 121, 123, 117 and 127 based on control data 115 received from access point 110, in an embodiment of the present invention, each of these communication devices can respond to its own motion data, such as motion data 113, to control its transmit and receive characteristics, without intervention from the access point. For example, if the communication device 117 determines it is moving out of range, it can increase its power level, and steer its antenna beam in the direction of the access point 110 and/or modify other protocol parameters to compensate for a possible lowering of signal to noise ratio, etc.
  • In an embodiment of the present invention, the communication devices 121, 123, 117 and 127 adjusts the manner in which position information is determined based on whether or not the wireless transceiver is transmitting. In particular, potential interference caused by the transmission could corrupt the GPS data received during this period. The present invention adjusts the determination of position information during transceiver transmissions to compensate for the potential loss or corruption of current GPS position data by, for instance, de-weighting the current GPS position data and relying instead on position data that is estimated based on prior GPS position and/or velocity data or based on motion data generated by an optional motion sensor.
  • While motion data 113 has been discussed above primarily with respect to the control of communications in a communications application and for gaming such as local or Internet gaming, motion data 113 generated in such a fashion can further be used in support of other applications such as position and navigation services, location-based services, authentication services and other applications where the position, orientation or location of the communication device 117 is useful or required. Particular attention to the use of communication device 117 in a separate gaming mode of operation will be discussed in greater detail in conjunction with FIG. 26-44. Further details including several other methods and implementations will be discussed in conjunction with FIGS. 4-25 that follow.
  • FIG. 4 presents a pictorial representation of a wireless network in accordance with an embodiment of the present invention. In particular, communication device 117 is a wireless telephone device or other device that includes a wireless telephony transceiver and that, in a telephony mode of operation, is capable of placing a receiving conventional wireless telephone calls, voice over internet protocol telephone calls, communicating via a wireless telephony protocol such as cellular voice or data protocol such as GSM, GPRS, AMPS, UMTS, EDGE or other wireless telephony protocol that can be used to communicate with a network 119, such as a wireless telephone or data network, the Internet or other network, via base station or access point 11 8. In an embodiment of the present invention, communication device 117 includes a GPS receiver and generates position information that is used by communication device 117 and/or network 119 for location-based services, for placing emergency calls such as 911 (e911) calls.
  • In addition, the position information can be used by communication device 110 for adjusting transmit, receive and antenna characteristics based on the position or motion of communication device 117, either by itself or based on information obtained from a base station/access point such as base station or access point 118 in a similar fashion to communication device 117 discussed in conjunction with FIG. 3. In an embodiment of the present invention, can optionally adjust the determination of position information during transceiver transmissions to compensate for the potential loss or corruption of current GPS position data by, for instance, de-weighting the current GPS position data and relying instead on position data that is estimated based on prior GPS position and/or velocity data or based on motion data generated by an optional motion sensor.
  • In addition, communication device 117 can be a dual mode or multi-mode device that can be used in a gaming mode of operation. In this mode, communication 117 uses one or more sensors, such as a microphone, button, joy-stick, thumb wheel, motion sensor, touch screen or photo sensor, for generating gaming data 66 in response to the actions of a user. In addition, the communication device 117 can us its wireless telephony transceiver to sends the gaming data 66 to a game device 115 in the gaming mode of operation.
  • For example, the game device 115 can be a game console, such as a home gaming console, set-top box, arcade game or other local game device that runs a game, such as a video game and generates display data, such as audio and/or video display data, that can be transferred to display device 125 for display. The display device can be a television, monitor, or display screen, with or without corresponding audio production equipment, that is either integrated in game device 115 or connected to game device 115 via a port such as a video, multimedia or graphics port. Communication device 117 can operate as a game controller, joystick, remote controller, simulated sword, simulated gun, or be a simulated helmet, a vest, a hat, shoes, socks, pants, shorts, gloves, racquet, paddle, bat, musical instrument, or other gaming object to produce gaming data 66 to interact with the game. Gaming data can be game commands and preferences, user selections, authentication data control data, motion data or other data associated with a user's access to, set-up, and operation of a game. In this fashion, a user can operate communication device 117 as a wireless telephone to place and receive telephone calls, surf the Web or download ringtones, etc. In addition, the user can operate communication device 117 in a gaming mode of operation to interact with one or more games provided by game device 115.
  • In an embodiment of the present invention, the wireless telephony receiver of communication device 117 communicates directly with a compatible transceiver or receiver included in game device 115. Given the proximity of these devices during normal gaming conditions, the wireless telephony transceiver of communication device 117 adjusts its transmit power to a low power state in the gaming mode of operation so that, when sending the gaming data 66, the communication device 117 reduces possible interference with the base station or access point 118 and other devices and further operates with reduced power consumption. In one mode of operation, the wireless telephony receiver of game device 115 can likewise send other gaming data back to communication device 117 in conjunction with the set-up and operation of a game, the establishment of communication between the game device 115 and the communication device 117, the authentication of a user of communication device 117, etc. This other gaming data can further include display data for display on the display device of communication device 117. When communicating signals or other gaming data back to communication device 115, game device 115 can likewise operate in a low power state, either permanently or on a case-by-case basis, to avoid interference with the base station or access point 118 and other devices.
  • FIG. 5 presents a pictorial block diagram representation of a communication device 117 in accordance with another embodiment of the present invention. In particular, an embodiment is shown that includes similar elements from the embodiment of FIG. 4 that are referred to by common reference numerals. As discussed in conjunction with FIG. 4, communication device 117 can operate in a telephony mode of operation and communicate with network, such as network 119, via a base station or access point 118. In addition, the wireless telephony transceiver of communication device 117 can, in a gaming mode of operation, send data to and/or receive data from the game device 115.
  • In this embodiment however, game device 115 is itself coupled to a network 119 via a narrow or broadband modem, network card or other interface that is capable of transceiving data with the network 119 on a wireless or wired basis. In this fashion, the game device 115 can operate in conjunction with communication device 117 to select gaming applications that are stored on network 119 either by downloading and executing these gaming application or by executing these applications on a gaming server or other device coupled to network 119. In this fashion, the user of communication device 117 and gaming device 115 can access a wider variety of games, receive game updates engage in multiplayer games, and execute gaming applications based on data received from network 119.
  • In another mode of operation, game device 115 can obtain conditional access information via the network 119. For instance, game device 115 can be located in an arcade or other public location where many users may access the game device. Users of communication devices, such as communication device 117, can subscriber to a service, either for a limited period or on an on-going basis, that allows the user to access the game device 115 in order to play one or more games. During an initial exchange between communication device 117 and game device 115 gaming data 66 is provided to game device 115 that includes passwords, logon identifiers or other conditional access data that can be authenticated by game device 115 via network 119 prior to allowing the user of communication device 117 to play the game.
  • FIG. 6 presents a pictorial block diagram representation of a communication device 117 in accordance with another embodiment of the present invention.

In addition, the wireless telephony transceiver of communication device 117 can, in a gaming mode of operation, send gaming data to and/or receive data from the game device 115.
  • In this embodiment, communication device 117 can further operate in a gaming mode of operation to send the gaming data 66 to the gaming device 115 by transmitting radio frequency signals via its wireless telephony transceiver to base station or access point 118 for communication with game device 115 over network 119. In particular, in implementations where game device 115 either does not include its own wireless telephony receiver or transceiver or the communication device 117 is out of range of the wireless telephony transceiver or receiver of game device 115, communication device 117 can nevertheless interact with the game device 115 to play a game.
  • As in the embodiment of FIG. 5, game device 115 is itself coupled to a network 119 via a narrow or broadband modem, network card or other interface that is capable of transceiving data with the network 119 on a wireless or wired basis. In this fashion, the communication device 117 can interact with network 119 to access game device 115. For example, during an initial exchange between communication device 117 and network 119 gaming data 66 is provided to network 119 to select a game device that is coupled to network 119, such as game device 115. The gaming data 66 can include passwords, logon identifiers or other conditional access data that can be authenticated by either network 119 or game device 115 prior to allowing the user of communication device 117 to play a game.

In this embodiment however, game device 115′ generates the display data 68 for display on a device, such as personal computer 129, that is separate from communication device 117 and is also capable of accessing game device 115′ via base station or access point 118 via network 119. While shown as a personal computer 129, the other device can similarly be implemented via a home game console, network coupled television or monitor, arcade game device or other device having a compatible display device for displaying display data 68 and further for communicating with network 119 on a wired or wireless basis.
  • In this embodiment, an initial exchange can take place between either communication device 117 or personal computer 129 to access game device 115′, to optionally authenticate the user, to set up the game and further to identify the communication device 117 as the source of gaming data 66 and the destination for other gaming data and the personal computer 129 as the destination for display data 68.
  • FIG. 9 is a schematic block diagram of an embodiment of an integrated circuit in accordance with the present invention. In particular, an RF integrated circuit (IC) 50 is shown that implements communication device 10, such as communication device 117 in conjunction with actuator, microphone 60, keypad/keyboard 58, memory 54, speaker 62, display 56, camera 76, antenna interface 52 and wireline port 64. In operation, RF IC 50 includes a multi-mode transceiver/GPS receiver 73 having RF and baseband modules for receiving GPS signals 43 and further a wireless telephony receiver for transmitting and receiving data RF real-time data 26 and non-real-time data 24 via an antenna interface 52 and antenna. The antenna can be a fixed antenna, a single-input single-output (SISO) antenna, a multi-input multi-output (MIMO) antenna, a diversity antenna system, an antenna array or other antenna configuration that optionally allows the beam shape, gain, polarization or other antenna parameters to be controlled.
  • As previously discussed, the multimode transceiver/GPS receiver 73 can operate in a telephony mode where the real-time data 26 and/or non-real-time data 24 include telephony data communicated with a telephony network. Multimode transceiver/GPS receiver 73 can further operate and in a gaming mode of operation where the real-time data 26 and/or non-real-time data 24 include gaming data 66, display data 68 and other data. As will be discussed further multi-mode transceiver/GPS receiver 73 for receiving and processing GPS signals in conjunction with either the telephony mode of operation, the gaming mode of operation or further in a dedicated GPS mode of operation fur use of communication device 10 in GPS positioning, navigation or other services.
  • In addition, RF IC 50 includes input/output module 71 that includes the appropriate interfaces, drivers, encoders and decoders for communicating via the wireline connection 28 via wireline port 64, an optional memory interface for communicating with off-chip memory 54, a codec for encoding voice signals from microphone 60 into digital voice signals, a keypad/keyboard interface for generating data from keypad/keyboard 58 in response to the actions of a user, a display driver for driving display 56, such as by rendering a color video signal, text, graphics, or other display data, and an audio driver such as an audio amplifier for driving speaker 62 and one or more other interfaces, such as for interfacing with the camera 76 or the other peripheral devices.
  • The actuator 48 can be a sensor such as a joy-stick or thumb wheel. Further the actuator 48 can include a photosensor that generates gaming data data based on an optical signal from a video display such as a video display associated in game console 115 or separate video display that operates based on display data 68. In this fashion, the optical signal can be used to generate data that represents position or orientation of the communication device 10. For instance, the optic sensor used on communication device 10 can generate optical feedback to determine if the communication device is pointed at particular object on the screen for games involving simulated guns, or objects whose orientation is important to the game and/or for use of the communication device 10 as a pointing device for selecting on-screen selections in conjunction with a user interface.
  • In operation, communication device 10 can generate gaming data, such as gaming data 66 in response to a user's interaction with microphone 60, actuator 48, keypad/keyboard 58, to provide game commands and preferences, user selections, authentication data, control data or other data associated with a user's access to, set-up, and operation of a game.
  • Power management circuit (PMU) 95 includes one or more DC-DC converters, voltage regulators, current regulators or other power supplies for supplying the RF IC 50 and optionally the other components of communication device 10 and/or its peripheral devices with supply voltages and or currents (collectively power supply signals) that may be required to power these devices. Power management circuit 95 can operate from one or more batteries, line power, an inductive power received from a remote device, a piezoelectric source that generates power in response to motion of the integrated circuit and/or from other power sources, not shown. In particular, power management module can selectively supply power supply signals of different voltages, currents or current limits or with adjustable voltages, currents or current limits in response to power mode signals received from the RF IC 50. While shown as an off-chip module, PMU 95 can alternatively implemented as an on-chip circuit.
  • In addition, RF IC 50 and is coupled to a motion sensor 175 that generates motion signals in response to motion of the mobile communication device. The GPS receiver of multi-mode transceiver/GPS receiver 73 receives GPS signals and generates GPS position data based on these GPS signals. Motion data generation module 55 generates motion data based on the motion signals and/or the GPS position data that can be included in gaming data 66 in the gaming mode of operation, that can be used in support of the telephony and GPS modes of operation. Various implementations of motion data generation module including many optional functions and features are presented in conjunction with FIGS. 12-18 and/or FIGS. 36-38 or as otherwise described herein.
  • Motion sensor 175 can be implemented via one or more one, two or three-axis accelerometers or one or more on-chip gyrating circuits implemented with microelectromechanical systems (MEMS) technology to form a piezoelectric gyroscope, a vibrating wheel gyroscope, a tuning fork gyroscope, a hemispherical resonator gyroscope, or a rotating wheel gyroscope that responds to inertial forces, such as Coriolis acceleration or linear acceleration, in one, two or three axes to generate motion data, such as a velocity vector in one, two or three dimensions and/or one, two or three orientations.
  • While motion sensor 175 is shown as a off-chip component and motion data generation module 55 is shown as being implemented on-chip, either of these units can be implemented either on-chip or off-chip, depending on the implementation.
  • In operation, the multi-mode transceiver/GPS receiver 73 generates an outbound RF signal from outbound data and generates inbound data from an inbound RF signal. Further, processing module 225 is coupled to the motion sensor 175, when included, and the dual mode transceiver/GPS receiver 73, and processes position information, generates the outbound data that includes the position information or motion data, and receives the inbound data that optionally includes data from a remote access point/base station to modify transmit and/or receive parameters in response to the position information that was transmitted.
  • As discussed in conjunction with FIGS. 3 and 4, the communication device 10, places and receives wireless calls through a wireless telephone network and/or a IP telephone system, via a base station, access point or other communication portal, operates through command by the processing module 225 to either respond directly to motion data, such as motion data 113, it generates from motion sensor 175 and/or the GPS receiver to control the transmit and receive characteristics of transceiver 73 or to respond to control data, such as control data 99 received from an access point or other station to control the transmit and receive characteristics of transceiver 73.
  • For example, if the communication device 10 determines it is moving out of range, it can increase its power level, and steer its antenna beam in the direction of the access point and/or modify other protocol parameters to compensate for a possible lowering of signal to noise ratio, modify its receiver sensitivity, etc. In addition, position information generated by GPS receiver and/or motion sensor 175 can be included in the outbound RF signal sent to a telephone network to support a 911 call such as an E911 emergency call.
  • In an embodiment of the present invention, the RF IC 50 is a system on a chip integrated circuit that includes at least one processing device. Such a processing device, for instance, processing module 225, may be a microprocessor, micro-controller, digital signal processor, microcomputer, central processing unit, field programmable gate array, programmable logic device, state machine, logic circuitry, analog circuitry, digital circuitry, and/or any device that manipulates signals (analog and/or digital) based on operational instructions. The associated memory may be a single memory device or a plurality of memory devices that are either on-chip or off-chip such as memory 54. Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, and/or any device that stores digital information. Note that when the RF IC 50 implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the associated memory storing the corresponding operational instructions for this circuitry is embedded with the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry. Motion data generation module 55, multi-mode transceiver/GPS receiver 73, and I/O module 71 can be implemented via hardware, or software and/or firmware operating in conjunction with processing module 225.
  • In further operation, the RF IC 50 executes operational instructions that implement one or more of the applications (real-time or non-real-time) attributed to communication devices 10 and 117 as discussed above and in conjunction with FIGS. 1-8.
  • FIG. 10 is a schematic block diagram of another embodiment of an integrated circuit in accordance with the present invention. In particular, FIG. 10 presents a communication device 30 that includes many common elements of FIG. 9 that are referred to by common reference numerals. RF IC 70 is similar to RF IC 50 and is capable of any of the applications, functions and features attributed to RF IC 50. However, RF IC 70 includes a separate wireless transceiver 75 for transmitting and receiving RF data 40 and RF voice signals 42, such as real-time data 26 and/or non-real-time data 24 and further a separate GPS receiver 77 for receiving GPS signals 43.
  • In operation, the RF IC 70 executes operational instructions that implement one or more of the applications (real-time or non-real-time) attributed to communication devices 10, 30 and 117 as discussed above and in conjunction with FIG. 1-9.
  • FIG. 11 is a schematic block diagram of another embodiment of an integrated circuit in accordance with the present invention. In particular, FIG. 11 presents a communication device 30′ that includes many common elements of FIG. 10 that are referred to by common reference numerals. RF IC 70′ is similar to RF IC 70 and is capable of any of the applications, functions and features attributed to RF ICs 50 and 70 as discussed in conjunction with FIGS. 1-10. However, RF IC 70′ operates in conjunction with an off-chip GPS receiver 77′ for receiving GPS signals 43.
  • In operation, the RF IC 70′ executes operational instructions that implement one or more of the applications (real-time or non-real-time) attributed to communication devices 10, 30, and 117 as discussed above and in conjunction with FIGS. 1-10.
  • FIG. 12 is a schematic block diagram of a GPS receiver 210 used to generate position in accordance with an embodiment of the present invention. In this embodiment, GPS receiver 210, such as GPS receiver 77, 77′ or multi-mode receiver 73 generates position information 186 that can be used by communication devices 10, 30, 30′ and/or 117 to generate gaming data 66 and optionally to control its own operation and/or to send to remote devices such as access point 110, a base station, telephone network or system, etc. for other purposes.
  • In particular, global positioning system (GPS) receiver 210 receives a GPS signal and that generates GPS position data 212 based on the GPS signal. GPS receiver 210 generates GPS position data and GPS data quality signal 216. In operation, GPS receiver 210 is coupled to recover a plurality of coarse/acquisition (C/A) signals and a plurality of navigation messages from received GPS signals 43. The GPS receiver 210 utilizes the C/A signals and the navigations messages to determine the position of the communication device.
  • In an embodiment of the present invention, motion data generation module 55 is implemented via sample and hold module 180 and weighting module 184. While sample and hold module 180 and weighting module 184 are shown as discrete modules, in an embodiment of the present invention, these modules can also be implemented in hardware, software or firmware using a processor such as processing module 225 or other processing elements.
  • In particular, GPS receiver 210 generates one or more clock signals. The clock signal(s) may also be used by the GPS receiver 210 to determine the communication device's position. GPS receiver 210 determines a time delay for at least some of the plurality of C/A signals in accordance with the at least one clock signal. The GPS receiver calculates a distance to a corresponding plurality of satellites of the at least some of the plurality of C/A signals based on the time delays for the at least some of the plurality of C/A signals. In other words, for each GPS signal 43 received, which are received from different satellites, the GPS receiver 210 calculates a time delay with respect to each satellite that the communication device is receiving a GPS RF signal from, or a subset thereof. For instance, the GPS receiver 210 identifies each satellite's signal by its distinct C/A code pattern, then measures the time delay for each satellite. To do this, the receiver produces an identical C/A sequence using the same seed number as the satellite. By lining up the two sequences, the receiver can measure the delay and calculate the distance to the satellite, called the pseudorange. Note that overlapping pseudoranges may be represented as curves, which are modified to yield the probable position.
  • GPS receiver 210 can calculate the position of the corresponding plurality of satellites based on corresponding navigation messages of the plurality of navigation messages. For example, the GPS receiver 210 uses the orbital position data of the navigation message to calculate the satellite's position. The GPS receiver 210 can determine the location of the RF IC 50, 70 or 70′ (and therefore communication device 10, 30, 30′ or 117) based on the distance of the corresponding plurality of satellites and the position of the corresponding plurality of satellites. For instance, by knowing the position and the distance of a satellite, the GPS receiver 210 can determine it's location to be somewhere on the surface of an imaginary sphere centered on that satellite and whose radius is the distance to it. When four satellites are measured simultaneously, the intersection of the four imaginary spheres reveals the location of the receiver. Often, these spheres will overlap slightly instead of meeting at one point, so the receiver will yield a mathematically most-probable position that can be output as GPS position data 212. In addition, GPS receiver 210 can determine the amount of uncertainty in the calculation that is output as the GPS data quality 216. In the event that the GPS receiver 210 loses lock or otherwise receives insufficient signal from enough satellites to generate a GPS of even minimal accuracy, a minimum value of the GPS data quality 216 can be assigned. A transmit indicator 238 is generated when a wireless transceiver section such as a wireless telephone receiver, wireless LAN transceiver or other wire transceiver transmits by generating an outbound RF signal from an outbound symbol stream. A minimum value of the GPS data quality 216 can also be assigned when the transmit indicator 238 is asserted, and the when the transmit indicator is deasserted, the calculated GPS data quality can be used as GPS data quality 216.
  • It should be noted that the GPS data quality 216 can include a binary value that has a first value that indicates the quality of the GPS data is greater than some minimum quality and a second value that indicates that either the transmit indicator 238 has been asserted or that the data quality is otherwise below some minimum value due to poor signal strength, loss of satellite reception, etc. Further, the GPS data quality 216 can be a multi-valued signal, that includes separate indications of signal quality including multiple quality levels, with or without a separate transmission indication.
  • In operation, the GPS position data 212 is weighted with a first weighting factor when the wireless transceiver section is generating the outbound RF signal to produce first weighted GPS position data. In addition, the GPS position data is weighted with a second weighting factor when the wireless telephone transceiver section is not generating the outbound RF signal to produce second weighted GPS position data, wherein the first weighting factor is less than the second weighting factor. Position information 186 is generated based on at least one of the first and second weighted GPS position data.
  • In an embodiment, a sample and hold module 180 stores a prior value of the GPS position data 212. When the transmit indicator 238 is deasserted and the GPS data quality 216 indicates an acceptable level of accuracy, weight module 184 weights the GPS position data 212 by a weighting factor that is one or substantially one and the output of the sample and hold module 180 is weighted by a weighting factor that is zero or substantially zero. In this case, the position information 186 is equal to or substantially the GPS position data 212. When the transmit indicator 238 is asserted as reflected in a minimum value of GPS data quality 216 or other indication, the value of the prior GPS position data is held-frozen at the last value before the transmit indicator was asserted or the last position that is known to include accurate position data. The weight module 184 weights the GPS position data by a weighting factor that is zero or substantially zero and the output of the sample and hold module 180 is weighted by a weighting factor that is one or substantially one. In this case, the position information 186 is equal to or substantially the prior GPS position data value held by the sample and hold module 180.
  • FIG. 13 is a graphical representation of position information determined in accordance with an embodiment of the present invention. In particular, an example of position information 186 is shown on a graph, in map/Cartesian coordinates, of position information that progresses from times t1-t8, corresponding to sample times or other discrete intervals used to generate and/or update position information 186. While the position information 186 is shown in two-dimensions, three-dimensional position data can likewise be generated.
  • The first three times t1-t3, position data is derived from GPS position data such as GPS position data 212. In this example, transmit indicator 238 is asserted for times t4-t5. At time t4, the GPS position data may be unreliable or inaccurate. In response to the assertion of the transmit indicator 238, the sample and hold module 180 holds the GPS position data 212 from time t3 and the weighting module adjusts the weighting, so that the position information 186 for time t4, and for the remaining duration of the time that transmit indicator 238 is asserted t5 is equal to the prior GPS position data at time t3. In this example, at time t6, the GPS data quality 216 reflects unacceptable data quality, for instance due to the time required for the GPS receiver 210 to recover from the dropout caused by transmission during the time period t4-t5. In this case, the sample and hold module 180 continues to holds the GPS position data 212 from time t3 and the weighting module retains the weightings from time t4-t5 and the position information 186 at time t6 is also equal to the prior GPS position data at time t3. At time t7 and t8, when the transmit indicator 238 is deasserted, and the GPS position data again becomes reliable, the GPS position data is used to generate the position information.
  • FIG. 14 is a schematic block diagram of a GPS receiver 210 used to generate position in accordance with an embodiment of the present invention. In this embodiment, GPS receiver 210, such as GPS receiver 77, 77′ or multi-mode receiver 73 generates position information 186 that can be used by communication devices 10, 30, 30′ and/or 117 to generate gaming data 66, to control its own operation or to otherwise send to remote devices such as access point 110, a base station, telephone network or system, etc. In particular, GPS velocity data is generated by difference module 214 based on the difference between successive samples of GPS position data 212. This GPS velocity data is held by sample and hold module 181 and used to estimate future positions based on the last know position and the last know velocity in the case of a dropout caused by either the assertion of the transmit indicator 238 or an otherwise unacceptable GPS data quality 216. In particular, in case of a dropout, prior GPS position data 216 is held by sample and hold module 180 and used as the initial condition for integrator 190. Prior GPS velocity data held by sample and hold module 181 is integrated during a dropout to form estimated position data that is weighted with a 1 during a dropout, while the GPS position data is weighted zero to form position information 192. After a dropout ceases and accurate GPS data 212 returns, the weighting module weights the GPS position data 212 with a 1 and the estimated position data with a zero to form position information 192.
  • In an embodiment of the present invention, motion data generation module 55 is implemented via sample and hold modules 180 and 181, difference module 214, integrator 190 and weighting module 184 that can be implemented in hardware, software or firmware using a processor such as processing module 225 or other processing elements.
  • FIG. 15 is a graphical representation of position information determined in accordance with an embodiment of the present invention. In particular, an example of position information 192 is shown on a graph, in map/Cartesian coordinates, of position information that progresses from times t1-t8, corresponding to sample times or other discrete intervals used to generate and/or update position information 192. While the position information 192 is shown in two-dimensions, three-dimensional position data can likewise be generated.
  • The first three times, position data is derived from GPS position data such as GPS position data 212. In this example, transmit indicator 238 is asserted for times t4-t5. At time t4, the GPS position data may be unreliable or inaccurate. In response to the assertion of the transmit indicator 238, the sample and hold module 180 holds the GPS position data 212 from time t3 and the sample and hold 181 holds the velocity at t3 to form an estimated velocity vector. The integrator 190 generates estimated position data at times t4-t6 based on the position and velocity at time at time t3. The weighting module adjusts the weighting for time t4, and for the remaining duration of the time that transmit indicator 238 is asserted and the dropout condition further persists, so that the estimated position data is weighted and the GPS position data 212 is deweighted in determining position information 192. At time t7 and t8, when the transmit indicator 238 is deasserted and the GPS position data again becomes reliable, the GPS position data 212 is used to generate the position information.
  • FIG. 16 is a schematic block diagram of a gyrating circuit 200 and GPS receiver 210 used to generate position and velocity information in accordance with an embodiment of the present invention. In this embodiment, gyrating circuit 200, such as motion sensor 175 and GPS receiver 210, such as GPS receiver 77, 77′ or multi-mode receiver 73 cooperate to generate position information 230 and velocity information 232 that can be used by communication devices 10, 30, 30′ and/or 117 to generate gaming data 66, to control its own operation or otherwise to send to remote devices such as access point 110, a base station, telephone network or system, etc.
  • In particular, an embodiment of motion data generation module 55 is shown where GPS receiver 210 generates GPS position data and GPS data quality signal 216 that includes or is otherwise based on transmit indicator 238 as previously discussed in conjunction with FIGS. 12-15. At the same time, gyrating circuit 200 generates a motion vector 202 that is integrated by integrator 204 based on an initial condition 208 that is either its own prior estimated position data 206 or the prior GPS position data 212. By adding the motion vector 202 to the prior position, new estimated position data 206 can be generated.
  • In this embodiment, the GPS data quality 216 is compared with a value, such as quality threshold 218 that corresponds to a level of quality that is roughly on par with accuracy of position information that can be estimated using the gyrator circuit 200. If the GPS data quality 216 compares favorably to the quality threshold, the position information 230 is selected by multiplexer 222 as the GPS position data 212 in response to the selection signal 215 from comparator 217. When the GPS data quality 216 compares unfavorably to the quality threshold 218, such as during a dropout condition and/or a time when transmit indicator 238 is asserted, the selection signal 215 from comparator 217 selects the position information 230 from the estimated position data 206. The estimated position data 206 is initially generated from the prior (good) value of the GPS position data 212 (delayed by delay 221) and the current motion vector 202. If the dropout condition persists, the integrator 204 generates new estimated position data 206 based on the current motion vector 202 and the prior estimated position 206, as selected by multiplexer 220 in response to selection signal 215. While an integrator 204 is shown in this configuration, low-corner frequency low-pass filters, integrators with additional filtration and/or other filter configurations could likewise be employed. For instance, estimated position data 206 can be generated based on a filtered difference between current motion vector values and either past GPS position data 212 or past estimated position data 206, to provide more accurate estimates, to reject noise and/or to otherwise smooth the estimated position data 206.
  • In a similar fashion, velocity information 232 is generated either from the gyrating circuit 200 or from the GPS receiver 210. In particular, when the GPS data quality 216 compares favorably to quality threshold 218, velocity information 232 is selected from a difference module 214 that generates a velocity from the difference between successive values of the GPS position data 212. If however, the GPS data quality 216 compares unfavorably to the quality threshold 218, the velocity information 232 is selected instead from the motion vector 202.
  • While shown in a schematic block diagram as separate modules, the integrator 204, difference module 214, comparator 217, and multiplexers 220, 222, and 224 can likewise be implemented as part of processing module 225 either in hardware, firmware or software.
  • FIG. 17 is a graphical representation of position information determined in accordance with an embodiment of the present invention. In particular, position information 230 is shown that shows a graph, in map/Cartesian coordinates, of position information that progresses from times t1-t8, corresponding to sample times or other discrete intervals used to generate and/or update position information 230. While the position information 230 is shown in two-dimensions, three-dimensional position data can likewise be generated.
  • The first three times, position data is derived from GPS position data such as GPS position data 212. The velocity information, as shown for this interval, is GPS velocity data that is derived by the difference between the GPS position data. In this example, a GPS signal dropout covers times t4-t6 due to poor signal quality, the assertion of transmit indicator 238, etc. At time t4 , the GPS position data may be unreliable or inaccurate, so the new position is estimated position data that is generated from the prior GPS position data at time t3, and updated by the current motion vector, such as motion vector 202 from the gyrating circuit. At times t5 and t6, the GPS position data still may be unreliable or inaccurate, so the new position is estimated position data that is generated from the prior GPS position data (in this case prior estimated positions), updated by the current motion vector. At time t7 and t8 , when the GPS position data again becomes reliable, the GPS position data is used to generate the position information.
  • FIG. 18 is a schematic block diagram of a gyrating circuit 200 and GPS receiver 210 used to generate position and velocity information in accordance with another embodiment of the present invention. In particular, an embodiment of motion data generation module 55 is shown that includes similar elements from FIG. 17 that are referred to by common reference numerals. In this embodiment however, data from the gyrating circuit 200 and GPS receiver 210 are blended, based on the GPS data quality 216. In particular, weighting modules 240, 242, and 244 are provided that form the position information 230, the velocity information 232 and the initial condition 208 based on a weighted average of the GPS and gyrator produced values, wherein the weighting coefficients are dynamically chosen based on the GPS data quality 216.
  • For instance, for the value of the GPS data quality 216 corresponding to the highest accuracy GPS data and the transmit indicator 238 is deasserted, the weighting coefficients can be chosen to maximize the weight of the GPS position 212, and to minimize the weight of the estimated position data 206 in calculating the initial condition 208 and the position information 230 and further to maximize the weight of the GPS velocity data 224, and to minimize the weight of the motion vector 202 in calculating the velocity information 232. Further, for the value of the GPS data quality corresponding to the lowest accuracy GPS data (including a dropout condition, and/or a time when transmit indicator 238 is asserted), the weighting coefficients can be chosen to minimize the weight of the GPS position 212, and to maximize the weight of the estimated position data 206 in calculating the initial condition 208 and the position information 230 and further to minimize the weight of the GPS velocity data 224, and to maximize the weight of the motion vector 202 in calculating the velocity information 232. Also, for intermediate values of the GPS data quality 216, intermediate weighting values could be used that blend the GPS data with the data derived from the gyrating circuit to generate more robust estimates of these values.
  • FIG. 19 is a schematic block diagram of an embodiment of RF transceiver 135 and GPS receiver 187 in accordance with the present invention. The RF transceiver 135, such as transceiver 75 includes an RF transmitter 139, and an RF receiver 137. The RF receiver 137 includes a RF front end 140, a down conversion module 142 and a receiver processing module 144. The RF transmitter 139 includes a transmitter processing module 146, an up conversion module 148, and a radio transmitter front-end 150.
  • As shown, the receiver and transmitter are each coupled to an antenna through an off-chip antenna interface 171 and a diplexer (duplexer) 177, that couples the transmit signal 155 to the antenna to produce outbound RF signal 170 and couples inbound signal 152 to produce received signal 153. Alternatively, a transmit/receive switch can be used in place of diplexer 177. While a single antenna is represented, the receiver and transmitter may share a multiple antenna structure that includes two or more antennas. In another embodiment, the receiver and transmitter may share a multiple input multiple output (MIMO) antenna structure, diversity antenna structure, phased array or other controllable antenna structure that includes a plurality of antennas. Each of these antennas may be fixed, programmable, and antenna array or other antenna configuration. Also, the antenna structure of the wireless transceiver may depend on the particular standard(s) to which the wireless transceiver is compliant and the applications thereof.
  • In operation, the transmitter receives outbound data 162 that includes non-realtime data or real-time data including gaming data in a gaming mode of operation, from a host device, such as communication device 10 or other source via the transmitter processing module 146. The transmitter processing module 146 processes the outbound data 162 in accordance with a particular wireless communication standard that can include a cellular data or voice protocol, a WLAN protocol, piconet protocol or other wireless protocol such as IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) to produce baseband or low intermediate frequency (IF) transmit (TX) signals 164 that includes an outbound symbol stream that contains outbound data 162. The baseband or low IF TX signals 164 may be digital baseband signals (e.g., have a zero IF) or digital low IF signals, where the low IF typically will be in a frequency range of one hundred kilohertz to a few megahertz. Note that the processing performed by the transmitter processing module 146 can include, but is not limited to, scrambling, encoding, puncturing, mapping, modulation, and/or digital baseband to IF conversion.
  • The up conversion module 148 includes a digital-to-analog conversion (DAC) module, a filtering and/or gain module, and a mixing section. The DAC module converts the baseband or low IF TX signals 164 from the digital domain to the analog domain. The filtering and/or gain module filters and/or adjusts the gain of the analog signals prior to providing it to the mixing section. The mixing section converts the analog baseband or low IF signals into up-converted signals 166 based on a transmitter local oscillation 168.
  • The radio transmitter front end 150 includes a power amplifier and may also include a transmit filter module. The power amplifier amplifies the up-converted signals 166 to produce outbound RF signals 170, which may be filtered by the transmitter filter module, if included. The antenna structure transmits the outbound RF signals 170 to a targeted device such as a RF tag, base station, an access point and/or another wireless communication device via an antenna interface 171 coupled to an antenna that provides impedance matching and optional bandpass filtration.
  • The receiver receives inbound RF signals 152, that may include display data, other gaming data of other real-time or non-real-time data, via the antenna and off-chip antenna interface 171 that operates to process the inbound RF signal 152 into received signal 153 for the receiver front-end 140. In general, antenna interface 171 provides impedance matching of antenna to the RF front-end 140, optional bandpass filtration of the inbound RF signal 152 and optionally controls the configuration of the antenna in response to one or more control signals 141 generated by processing module 225.
  • The down conversion module 142 includes a mixing section, an analog to digital conversion (ADC) module, and may also include a filtering and/or gain module. The mixing section converts the desired RF signal 154 into a down converted signal 156 that is based on a receiver local oscillation 158, such as an analog baseband or low IF signal. The ADC module converts the analog baseband or low IF signal into a digital baseband or low IF signal. The filtering and/or gain module high pass and/or low pass filters the digital baseband or low IF signal to produce a baseband or low IF signal 156 that includes a inbound symbol stream. Note that the ordering of the ADC module and filtering and/or gain module may be switched, such that the filtering and/or gain module is an analog module.
  • The receiver processing module 144 processes the baseband or low IF signal 156 in accordance with a particular wireless communication standard that can include a cellular data or voice protocol, a WLAN protocol, piconet protocol or other wireless protocol such as IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) to produce inbound data 160 that can include non-realtime data, realtime data an control data. The processing performed by the receiver processing module 144 can include, but is not limited to, digital intermediate frequency to baseband conversion, demodulation, demapping, depuncturing, decoding, and/or descrambling.
  • GPS receiver 187, such as GPS receiver 77, includes an RF front-end 140′ and down conversion module 142′ that operates in a similar fashion to the modules described in conjunction with RF receiver 137, however, to receive and convert GPS RF signals 143 into a plurality of down converted GPS signals 159. Note that the GPS RF signals 143 may be one or more of: an L1 band at 1575.42 MHz, which includes a mix of navigation messages, coarse-acquisition (C/A) codes, and/or encryption precision P(Y) codes; an L2 band at 1227.60 MHz, which includes P(Y) codes and may also include an L2C code; and/or an L5 band at 1176.45 MHz. Further note that the GPS RF signals 143 can include an RF signal from a plurality of satellites (e.g., up to 20 different GPS satellites RF signals may be received).

  • FIG. 39 is a schematic block diagram of a side view of another embodiment of a gaming system in accordance with the present invention. A gaming object 610′ is provided that be implemented via gaming object 610, 611 or communication device 117 or via another gaming object that generates motion data 602 and that wirelessly transmits the motion data 602 to a game console 600′ over a wireless communication path. Game console 600 can be similar to game console 600. The wireless communication path can be a implemented in accordance with one or more wireless telephony transceivers that operate in accordance with a wireless telephony protocol, via RFID communication, or via other wireless communications.
  • In this embodiment however, either the gaming object 610′ or the game console 600′ operates in accordance with a motion prediction model, for instance, that represents a biomechanical trajectory 800 of the user 606 or more specifically the user's body, during the playing of a game. The use of this motion prediction model can be used generate trajectory data that more accurately represents the motion of gaming object 610′ or the body of user 606 with optionally less motion data 602 being communicated over the wireless communication path 604.

In particular, a gaming system is shown that includes game console 600′ and gaming object 610′. Gaming object 610′ includes one or more motion sensors 616 for generating motion data, such as motion data 602 in response to the actions of a user, such as user 606. Motion sensor 616 can include an on-chip gyrator or accelerometer or other position or motion sensing device along with other driver circuitry for generating motion data 602 based on the actions of the user 606.
  • Transceiver 620 wireless transmits the motion data 602 to the transceiver 631 of game console 600′. Transceivers 620 and 631 can operate via a wireless telephony protocol when, for instance, gaming object 610′ is implemented via communication device 117. However, or wireless communication paths cal likewise be used such as a Bluetooth communication interface or other short range communication path.
  • In an embodiment of the present invention an RFID communication path is employed where the transceiver 620 is coupled to receive an RF signal initiated by game console 600′, such as a 60 GHz RF signal or other RF signal. In a similar fashion to a passive RFID tag, millimeter wave transceiver 620 converts energy from the RF signal into a power signal for powering the millimeter wave transceiver 620 or all or some portion of the gaming object 610′. By the gaming object 610′ deriving power, in while or in part, based on RF signal, gaming object 610′ can optionally be portable, small and light. In this embodiment, millimeter wave transceiver 620 conveys the motion data 602 back to the game console 600′ by backscattering the RF signal based on motion data 102.
  • Game console 600′ includes an interface module 632 for coupling to the gaming object 610′. In particular, interface module 632 includes a transceiver 631 or receiver that receives the motion data 602. As discussed above, transceiver 631 can be a millimeter wave transceiver that transmits an RF signal for powering the gaming object 610′. In this case, millimeter wave transceiver 631 demodulates the backscattering of the RF signal to recover the motion data 602.
  • Similar to game console 600, game console 600′ includes a memory 624 and processor 622 that are coupled to interface module 632 via a bus 625. While not expressly shown, game console 600′ can further include a network interface, such as network interface 627, that provides a coupling to a network, such as network 119 as discussed in conjunction with FIGS. 4-8. In particular, this network interface itself can be used to receive data such as motion data 602 or other gaming data, such as gaming data 66 from the gaming object 610′, to send display data or other gaming data back to the gaming object 610′ or a remote display device, and further to communicate authentication data, download game applications, run remote game applications, etc.
  • Game console 600′ further includes a trajectory generation module 625 that generates trajectory data based on the motion data 602 and based on a motion prediction model provided by model generation module 635. As discussed in conjunction with FIG. 39, the motion prediction model represents a biomechanical trajectory of a user of the gaming object 610′ in accordance with a game.
  • In an embodiment of the present invention, the model generation module 635 generates the motion prediction model based on a game selection signal from processor 622 that indicates which, of a plurality of games, has been selected and that is being executed. For instance, in a motion prediction model can operate to provide one or more biomechanical trajectories that correspond to the game being played. The trajectory generation module 625 can generate trajectory data that “fits” the motion data 602 based on this trajectory.
  • Consider an example where user 606 is playing a bowling game. The gaming object 610′ is placed in his or her hand and is swung to simulate the throwing of the bowling ball. The gaming object 610′ generates motion data 602 based on the motion of gaming object 610′ during the simulated throw and sends the motion data 602 to the game console 600′. In this example, the motion prediction model can fit the motion data 602 to a trajectory that represents the user 606 throwing a bowling ball. In effect, the trajectory generation module 625 fits the model data 602 to one of a family of “bowling ball throw” trajectories having, for instance, different speeds, different angles, differing amounts of spin/curve. The trajectory model generation module 625 then generates the trajectory data based on either the selection of one of a discrete number of possible trajectories or the identification of particular trajectory parameters that describe a particular trajectory. The trajectory data can then be used by the processor 622 to generate a display signal 628 that shows the particular bowling ball throw on the screen and the resulting knocking down of pins (if any).
  • Consider a further example where user 606 is playing a tennis game. The gaming object 610′ is placed in his or her hand and is swung to simulate the motion of the tennis racquet in stroking a tennis ball. The gaming object 610′ generates motion data 602 based on the motion of gaming object 610′ during the simulated motion and sends the motion data 602 to the game console 600′. In this example, the motion prediction model can fit the motion data 602 to a trajectory that represents the user 606 hitting the ball. In effect, the trajectory generation module 625 fits the model data 602 to one of a family of “tennis swings” trajectories having, for instance, forehand shots, backhand shots, drop shots, overhead shots, serves, etc. having different speeds, different angles, differing amounts of spin/curve. The trajectory model generation module 625 then generates the trajectory data based on either the selection of one of a discrete number of possible trajectories and/or the identification of particular trajectory parameters that describe a particular trajectory. The trajectory data can then be used by the processor 622 to generate a display signal 628 that shows the particular tennis shots on the screen.
  • While described above in the context of bowling and tennis, the model generation module 635 can operate to generate motion prediction models with the respect to a wider range of games that involve simulated combat, dancing, other sports, racing and other game activities where the motion data 602 can be used to generate trajectory data that is used in the execution of the gaming application to simulate the motion of the user 606. While the description above has focused on motion data 602 received from gaming object 610′ derived from a single motion sensor 616, a plurality of motion sensors could likewise be employed to simulate more complex motion. Further, motion data 602 can be received from a gaming object 611 that collects motion signals from a plurality of remote motion sensing devices 640. In this fashion, more complex trajectories including multiple body parts of user 606 can be determined based on the motion data 602 to simulate a jump, throw, running, or other motion of the user's body in the context of one or more games.
  • In an embodiment of the present invention, the model generation module 635 generates a motion prediction model, such as a finite element model that corresponds to the position and/or motion of a plurality of body parts of user 606. In this fashion, trajectory data of the arms, legs, hands, head, etc. of the user 606 can be determined by trajectory generation module 625 based on motion data 602. In particular, motion data 602 corresponding to a plurality of remote motion sensing devices, such as remote motion sensing devices 526 associated with different portions of the body of user 606, can be fit to the motion prediction model of a body to simulate complex motion of the body in the context of one or more games.
  • In operation, processor 622 executes one or more routines such as an operating system, utilities, and one or more applications such as video game applications or other gaming applications that operate based on the trajectory data and optionally other gaming data received from gaming object 610′, that optionally generate other data for transmission back to the gaming object 610′, and produce video information, further based on the trajectory data, such as display data that can be converted to display signal 628 via driver 626. The driver 626 can be a signal generation module or other video processor for use by an integrated display device or a display device coupled to game console 600′ via an optional display port, such as a video connector, component video port, S-video connector, parallel or serial video port, HDMI port or other video port.
  • Processor 622 can include a dedicated or shared processing device. Such a processing device may be a microprocessor, micro-controller, digital signal processor, microcomputer, central processing unit, field programmable gate array, programmable logic device, state machine, logic circuitry, analog circuitry, digital circuitry, and/or any device that manipulates signals (analog and/or digital) based on operational instructions. The memory 624 can be a single memory device or a plurality of memory devices. Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, and/or any device that stores digital information. Note that when the processor 622 implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the memory storing the corresponding operational instructions is embedded with the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry. While a particular bus architecture is shown, alternative bus architectures including architectures having two or more buses or direct connectivity between the various modules of game console 600′, can likewise be employed within the broad scope of the present invention.
  • FIG. 41 is a graphical representation of trajectory data determined in accordance with an embodiment of the present invention. In particular, example trajectory data 904 is presented that corresponds to a three-dimensional trajectory that is based on motion data 902, such as motion data 602 from a single motion sensor. While the motion data 902 and trajectory data 904 are shown in the context of a Cartesian coordinate system, other coordinate systems can likewise be employed.
  • In this embodiment, trajectory generation module 625 generates the trajectory data 904 by interpolating the motion data 902 based on the motion prediction model. In this case, the motion prediction module can include a mathematical function such as a linear function, a trigonometric function, polynomial function of other function that is fit to the motion data 902 using a curve-fitting technique and used to interpolate trajectory data. In this fashion, motion data collected at lower resolution or a lower data rate can be used to generate trajectory data at a higher resolution or a higher data rate to simulate the motion of the user 606 in the context of a game.
  • For example, motion data 902 corresponding to a simulated golf swing can be collected from a gaming object, such as gaming object 610, 610′ or 611, at a data rate of 10 samples per second. This motion data 902 can be fit to a mathematical function that represents the biomechanical trajectory of possible golf swings and used to generate interpolated trajectory data 904 at a higher data rate such as 50 samples per second for the rendering of a smooth golf swing when presented on a video display.
  • FIG. 42 is a graphical representation of trajectory data determined in accordance with another embodiment of the present invention. In particular, example trajectory data 908 is presented that corresponds to a three-dimensional trajectory that is based on a model trajectory derived from motion data 602 from a single motion sensor. While the trajectory data 908 is shown in the context of a Cartesian coordinate system, other coordinate systems can likewise be employed.
  • In one example, the motion data 602 includes position data that is used by trajectory generation module 625 to select a best-fit model trajectory 906 of a finite number of possible trajectories generated by model generation module 635. Considering again the case of a simulated golf swing, motion data can be collected from a gaming object, such as gaming object 610, 610′ or 611, and compared to each of the a finite number of possible trajectories generated by model generation module 635 corresponding to a finite number of possible golf swings. The motion data 602 can be compared to each possible trajectory to determine the model trajectory 906 that provides the best fit, such as best least squares fit, smallest absolute deviation or other best fit to the motion data 602. Once the model trajectory 906 is determined, trajectory generation module 625 generates the trajectory data 908 in accordance with the selected model trajectory 906.
  • In a further example, motion data 602 include a plurality of model parameters of the motion prediction model, such as polynomial coefficients of a polynomial trajectory, or other coefficients or model parameters of a mathematical function that describe the motion of one or more motion sensors. In this embodiment, trajectory generation module 925 generates the model trajectory 906 based on the model parameters included in the motion data 602 and, in turn, generates the trajectory data 908 based on the model trajectory.
  • FIG. 43 is a graphical representation of trajectory data determined in accordance with another embodiment of the present invention. In particular, example trajectory data 912 is presented that corresponds to a three-dimensional trajectory that is based on differential motion data. In this example motion data 602 includes motion vectors 910 that describe the magnitude and direction of the motion. Trajectory generation module 625 generates a current position for the trajectory data 912 based on a prior position of the trajectory data 912 and further based on this differential motion data. While the motion vectors 910 and trajectory data 912 are shown in the context of a Cartesian coordinate system, other coordinate systems can likewise be employed.

Motion data generation module 645 generates motion data 603 based on the motion signals and based on a motion prediction model supplied for instance by model generation module 635. A transmitter or transceiver 620 is coupled to sends the motion data 603 to a game device 607 such as game console 600 or 600′ or game device 115 or 115′.
  • In this embodiment, the motion data generation module 645, such as motion data generation module 55, can generate motion data 603, such as motion data 602, motion data 902 and/or motion vectors 910. For instance, the motion data 603 can include a plurality of model parameters of the motion prediction model. The motion prediction model can include a polynomial trajectory and the plurality of model parameters include a plurality of polynomial coefficients.

  • In addition, model generation module can selects a data rate for the motion data based on the game selection signal. For example in a game where fast motion such as a golf swing is expected, a fast data rate can be selected for more frequent sampling of motion signals from motion sensor 616. In other games such as a chess game that simulates the motion of a user's hand to pick and place a chess piece, a slower data rate can be employed to, for instance, save bandwidth. One of a plurality of data rates or direct sampling rates can be selected based on the desired motion accuracy and the expected speed of motion for a particular game that has been selected.

However, if the remote motion sensing devices 526 each operate in accordance with a single protocol, and the RFID reader is not used by communication device 117 for other purposes, such as conditional access, payment transaction, etc, this flexibility can be omitted.
  • In operation, once the particular RFID standardized protocol has been selected for communication with one or more RFID tags, such as RFID tag 735, the protocol processing module 540 generates and provides digital data to be communicated to the RFID tag 735 to the encoding module 542 for encoding in accordance with the selected RFID standardized protocol. This digital data can include commands to power up the RFID tag 735, to read motion data or other commands or data used by the RFID tag in association with its operation. By way of example, but not limitation, the RFID protocols may include one or more line encoding schemes, such as Manchester encoding, FMO encoding, FM1 encoding, etc. Thereafter, in the embodiment shown, the digitally encoded data is provided to the digital-to-analog converter 544 which converts the digitally encoded data into an analog signal. The RF front-end 546 modulates the analog signal to produce an RF signal at a particular carrier frequency that is transmitted via antenna 560 to one or more RFID tags, such as RF ID rag 735. The antenna 560 can include a near-field coil.
  • The RF front-end 546 further includes transmit blocking capabilities such that the energy of the transmitted RF signal does not substantially interfere with the receiving of a back-scattered or other RF signal received from one or more RFID tags via the antenna 560. Upon receiving an RF signal from one or more RFID tags, the RF front-end 546 converts the received RF signal into a baseband signal. The digitization module 548, which may be a limiting module or an analog-to-digital converter, converts the received baseband signal into a digital signal. The predecoding module 550 converts the digital signal into an encoded signal in accordance with the particular RFID protocol being utilized. The encoded data is provided to the decoding module 552, which recaptures data, such as user data 698 therefrom in accordance with the particular encoding scheme of the selected RFID protocol. The protocol processing module 540 processes the recovered data to identify the object(s) associated with the RFID tag(s) and/or provides the recovered data to the processor 622 for further processing.

  • In operation, the power generating circuit 740 generates a supply voltage (VDD) from a radio frequency (RF) signal that is received via antenna 754. The power generating circuit 740 stores the supply voltage VDD in capacitor C1 and provides it to modules 744, 746, 748, 750, 752.
  • When the supply voltage VDD is present, the envelope detection module 752 determines an envelope of the RF signal, which includes a DC component corresponding to the supply voltage VDD. In one embodiment, the RF signal is an amplitude modulation signal, where the envelope of the RF signal includes transmitted data. The envelope detection module 752 provides an envelope signal to the comparator 750. The comparator 750 compares the envelope signal with a threshold to produce a stream of recovered data.
  • The oscillation module 744, which may be a ring oscillator, crystal oscillator, or timing circuit, generates one or more clock signals that have a rate corresponding to the rate of the RF signal in accordance with an oscillation feedback signal. For instance, if the RF signal is a 900 MHz signal, the rate of the clock signals will be n*900 MHz, where “n” is equal to or greater than 1.
  • The oscillation calibration module 748 produces the oscillation feedback signal from a clock signal of the one or more clock signals and the stream of recovered data. In general, the oscillation calibration module 748 compares the rate of the clock signal with the rate of the stream of recovered data. Based on this comparison, the oscillation calibration module 748 generates the oscillation feedback to indicate to the oscillation module 744 to maintain the current rate, speed up the current rate, or slow down the current rate.
  • The processing module 746 receives the stream of recovered data and a clock signal of the one or more clock signals. The processing module 746 interprets the stream of recovered data to determine a command or commands contained therein. The command may be to store data, update data, reply with stored data, verify command compliance, retrieve user data 698 from memory 900, send an acknowledgement, etc. If the command(s) requires a response, the processing module 746 provides a signal to the transistor T1 at a rate corresponding to the RF signal. The signal toggles transistor T1 on and off to generate an RF response signal that is transmitted via the antenna. In one embodiment, the RFID tag 735 utilizing a back-scattering RF communication.
